For converting the static PSD designs into dynamic HTML templates, there are many paid and free tools available on the web. These tools boast of migrating the Photoshop designs to HTML within hours or even in minutes. But the fact is that such tools have often being reported as prone to errors and a waste of time and money by the users of these tools.

It is just not right to imagine that an automated tool can match the precision and accuracy of a developer who hand codes the HTML markups. With PSD to HTML conversions on a rise, these tools often attract the webmasters who try them out to save time. However, hand coded HTML is better in terms of quality and reliability for numerous reasons. In this article, we will discuss some of the major disadvantages of using an online software or tool for converting PSD designs to an HTML template.

To begin with, you cannot expect a pixel perfect slicing with an automated tool. This is one of the major drawbacks of choosing an online converter. On the other hand, when an HTML developer writes the codes by himself, a pixel perfect approach is always followed as a part of the development. The highest quality web conversion accounts for retina optimized markups, while maintaining the integrity of the website.

An online conversion tool or software generates hard code. These kind of codes are complex and do not match up with the hand coded HTML markups. If we compare a similar program generated by an automated tool and a hand coded one, you will find that automated codes are not suitable for professional web projects. These codes fail to perform when used for content management systems and are frequently reported with crash and bugs.

To check the authenticity of a conversion, the W3C validator is a renown tool. When you test the code generated from an online tool, it does not get approved, which means that the code is not SEO friendly and will not assure cross-browser and cross-device compatibility. 

Online tools are difficult to customize or tweak as per the project requirements by a developer. Professional HTML developers have confirmed it time and again over various discussion portals that online HTML markups are hard to understand and edit and have a lot of Junk Code, which deploy the usability factor of such codes. In other words, professional front-end developers do not approve of the online conversion tools.

Whenever a PSD to HTML conversion is considered, one of the key aspects is to achieve mobile responsiveness. It is often observed that the markups generated by online tools are not of greatest quality. There are variations in website display over different browsers and screen resolutions, which is a negative sign of precise conversion.

In the end, it is obvious that one should avoid online converters for converting their Photoshop designs to HTML. As per the latest updates by Google, W3C compliance, responsiveness, are some of the must have elements of a website, which is only possible with hand coding by a professional developer.
